Unclear message when proxy is needed

[jesus2099]

From some places, I need to use the proxy command line parameter.
Sometimes I forget this and the error I get is very confusing, usually I am not able to understand why it fails before some hours of trying many silly things.

youtube-dl any-youtube-ID

In fact I have to use youtube-dl --proxy my.proxy.fr:80 any-youtube-ID (for instance) and it works. But the error message had nothing to help me finding this solution. :)

Post the full output of youtube-dl when run with --verbose and --dump-pages options.
